A strong foundation is important when siting a garden building.
Dunster House would recommend a flat, level concrete base. If you are unsure about building your concrete base we would recommend that you consult an experienced tradesman. Please note that the base needs to be level with no run off, since the building will provide this.
If you prefer not to construct a concrete base, we have designed an excellent foundation systems that work well with our garden buildings: the Premium RapidGrid foundations.
The Rapid Foundation System is a cost effective and environmentally friendly alternative to concrete foundations. Generally costing much less than a concrete base would, the Rapid Foundations do not ruin the surrounding soil and need very little soil to be removed compared to if you were laying a concrete base.
The RapidGrid Foundations are designed to work in medium firm ground conditions, and are suitable for the majority of gardens. Please be aware that they are not suitable for areas prone to water logged conditions, marsh, peat or recently disturbed ground. If you are unsure if your ground is suitable for foundations which will exert approx. 17Kpa of pressure, please talk to a local geotechnical engineer prior to purchasing.
(You can level the ground under the grids by moving earth.)
If your ground conditions are not suitable for the Premium RapidGrid foundation due to steep slopes or unstable ground then you may find reinforced concrete a better option, as all garden buildings need to be constructed on a flat, level surface.
When laying a concrete foundation for your garden building we suggest you add 100mm all the way around the sizes given for the building you have purchased. This will help spread the weight of the building and help ensure that if the base is slightly out of square that the building will still fit on the base. For example:
Please note: We do not offer installation on any foundation systems.
